TOY CONSTRUCTION-BLOCKS.

Application filed January 20, 1913. Serial No. 743,073.

To all whom it may concern:

Be it known that I, Anrmm C. Giuliani, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invente l a new and useful Improvement in Toy "onstruction-Blocks; and I do hereby d'clare the following, when taken in conncctio with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a face View of a toy construction block constructed in accordance with my invention. Fig. 2 an end view of the same. Fig. 3 a perspective view showing several blocks connected together. Fig.4: a sectional view on the line a-b of Fig. 3. Fig. 5 a perspective view of the couplingpiece, detached.

This invention relates to an improvement in toy construction blocks, the object being to provide blocks by which toy structures of various kinds may be erected, the blocks simulating what is known as steel construction; and the invention consists in the construction as hereinafter described and particularly pointed out. in the clain'is.

In carrying out my invention, I Form the blocks from a strip of sheet metal 2 preferably fori'ned on opposite sides with inwardly turned flanges 3. Preferably portions of the central portion of the strip will be cut out forming openings t leaving diagonal sections 5 simulating the appearance of steel beams, though it is apparent that the character of the stamping may be varied at will, or the strips may be left uncut. In uniting these strips, four strips 7, 8, i) and 10 are arranged as shown in Fig. 4 of the drawings around a U-shaped couplii'ig-picce (3 so as to form a rectangular block, the flanges oi' the strips 7 and 8 extending over the face of the strips 9 and 10, while through the strips 7 and S and through the sides of the coupling-piece (J a bolt 11 is passed by which the four sections are intcrloclu-d with the coupling-piece. The bolt may-be held in place by'a U-shaped clip 12 as clearly shown in Fig. 3 oil the drawings,n* the boltmay be threaded and a nut applied thereto. \Vhen arranging onescction at right angles to another section, or for supporting the lower end of one section, an an le-piece 13 may be employed as shown in Big. 3 of the drawings, this angle-piece being secured by bolts extending through the perforations let in opposite strips. \Vith a number of these strips or blocks various structures may be erected, such as frames for buildings, bridges, derricks, etc. These blocks or strips are readily stamped from sheet metal and can be packed into very small space for transportation. By providing the strips with the inwardly turned flanges, the strips .are strengthened and two or more strips may be connected end to end so as to form a long rigid strip.

1. Toy construction blocks comprising strips having inwardly turned flanges said strips provided at opposite ends with perforations, combined with U-shaped couplingpieces having perforations adapted to aline with the perforations in the strips, and bolts adapted to extend through the strips and cmipling-pieces, whereby four strips may be connected with a coupling-piece.

2. Toy construction blocks comprising strips having inwardly turned llangcs said strips provided at opposite ends with perforations, combined with U-shapcd couplingpieccs having perforations adapted to aline with perforations in two oi the strips, bolts adapted to pass through two of the strips and the couplingpicce between them. and a U-shapcd clip adapted to be engaged with the free end of the bolt whereby several strips are interlocked.

3. Toy construction blocks comprising strips of sheet metal formed with inwardly turned edges and provided at opposite ends with perforations, U -shapcd couplingpicccs around which four strips may be placed, means For interlocking said strips with the coupling-piece, and up angle iron adapted to connect two or more blocks.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
